    {
        $rndId = crypt(uniqid(rand(),1));
        $rndId = strip_tags(stripslashes($rndId));
        $rndId = str_replace(array(".", "$"),"",$rndId);
        $rndId = strrev(str_replace("/","",$rndId));
            if (!is_null($rndId)){
            return strtoupper(substr($rndId, 0, $length));
            }
        return strtoupper($rndId);
    }
    /* create unique coupan code */

        $productId  = (int) $this->getRequest()->getParam('id'); 
        $discountprice=$_POST['product']['discountprice']; 
        $model = Mage::getModel('salesrule/rule');
        $couponCode=generateUniqueId(8);
        $model->setName($couponCode);

Here is the perfect code for applying discount to specific product..I found the solution..This code is working fine for applying discount to specific product.

function generateUniqueId($length = null)
    {
        $rndId = crypt(uniqid(rand(),1));
        $rndId = strip_tags(stripslashes($rndId));
        $rndId = str_replace(array(".", "$"),"",$rndId);
        $rndId = strrev(str_replace("/","",$rndId));
            if (!is_null($rndId)){
            return strtoupper(substr($rndId, 0, $length));
            }
        return strtoupper($rndId);
    }
    /* create unique coupan code */
        $productId  = (int) $this->getRequest()->getParam('id'); 
        $sku=$this->getRequest()->getParam('sku');
        $discountprice=$_POST['product']['discountprice'];

From what I can tell of the discount system you will need to do the following before saving the rule. As you can see it works by searching for any cart product with a specific SKU.

$sku = 'ABCD';            // Put your product SKU here
$found = Mage::getModel('salesrule/rule_condition_product_found')
         ->setType('salesrule/rule_condition_product_found')
         ->setValue(1)           // 1 == FOUND
         ->setAggregator('all'); // match ALL conditions
$model->getConditions()->addCondition($found);
$skuCond = Mage::getModel('salesrule/rule_condition_product')
           ->setType('salesrule/rule_condition_product')
           ->setAttribute('sku')
           ->setOperator('==')
           ->setValue($sku);
$found->addCondition($skuCond);

This is the answer of my own question:
